I was curious if anyone knows of or does this service and how much? I'm at a cross roads. And think it's best to just take the plunge. While I need to buy tires and rims anyways... Per John Freund build thread. To run RPF1 - 18×10.5 +15 "Modified front and rear knuckles for inboard tire clearance (this is how I can run the above wheel/tire combos) , currently still requres 5mm spacer in rear"
